Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published on
any non-marine arthropod taxon. Manuscripts considered for publication include, but are not limited to,
systematic or taxonomic studies, revisions, nomenclatural changes, faunal studies, book reviews, phylogenetic analyses, biological or behavioral studies, etc. Insecta Mundi is widely distributed, and referenced or abstracted by several sources including the Zoological Record, CAB Abstracts, etc.
As of 2007, Insecta Mundi is published irregularly throughout the year, not as quarterly issues. As
manuscripts are completed they are published and given an individual number. Manuscripts must be
peer reviewed prior to submission, after which they are again reviewed by the editorial board to insure
quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology.

Introduction
Based on material from various collections, new species within the tribes Piezocerini, Hexoplonini,
Ibidionini (Tropidiina), Rhinotragini and Rhopalophorini are described.
Among Cerambycinae with finely faceted eyes, two species of Gorybia Pascoe, 1866 (Piezocerini) are
described. This genus was reviewed by Martins (1976), with 32 species at the time. It was once again
reviewed by Martins (2006), adding colored photographs for many species. Martins and Galileo (2007a)
added G. montana, and in 2008, Galileo and Martins described G. quadrispinosa.
A new species is described in Calycibidion Martins, 1971 (Hexoplonini), which had only included two
species so far. Hexoplonini was reviewed by Martins (2006).
Two species are described in Tropidion Thomson, 1867 (Ibidionini, Tropidiina) a speciose genus which
was reviewed by Martins (1968), when it included 64 species; it was once again reviewed by Martins and
Galileo (2007b), comprising 69 species in South America.
Hexoplonini Martins, 2006 and Tropidina Martins and Galileo, 2007 are nomina nuda by article 16.2
of the ICZN (Bousquet et al., 2009). To validate these tribes, Hexoplon Thomson, 1864 and Tropidion
Thomson, 1867, are designated as the type genera of Hexoplonini and Tropidiina, respectively.
In Rhinothragini, one species of Ommata (Ommata) White, 1855 is described. This subgenus had so
far included seven species (Monné and Hovore, 2005). Concerning Rhopalophorini, one species was added
to the genus Cosmisoma Audinet-Serville, 1834, which was reviewed by Monné and Magno (1988).

Diagnosis. Tropidion boliviensis sp. nov. is similar to Tropidion fairmairei (Gounelle, 1909) by the
coloring pattern and dense pronotum pubescence. It differs through its upper ocular lobes, with three
rows of ommatidia, pronotum glabrous near the anterior margin, with a pronounced and glabrous centroposterior tubercle, elytra with rough punctures and its anterior spot on the elytra, which prolongs towards the margin without reaching it.
In T. fairmairei, the superior ocular lobes present four rows of ommatidia, the pronotum is pubescent

rough punctures and the anterior elytra spot is rounded.
Rhinotragini

(Figure 6)
Description. Head reddish; antennal tubercles black. Frons moderately punctate (32 x), covered by a
shining, golden-yellow pubescence. Anterior region of the vertex, between the antennal tubercles, with
same kind of pubescence. Occiput punctate. Malar area shorter than the lower ocular lobe (female).

Tibiae, pro- and mesotarsi black. Metatarsomeres I-IV white; metatarsomere V white at the base and
reddish at the apex. Urosternites black covered by a whitish pubescence.
Measurements in mm. Total length, 8.5; prothorax length, 2.1; largest prothoracic width, 1.6; anterior prothoracic width, 1.1; elytra length, 6.0; humeral width, 1.9.

Diagnosis. Concerning antennomeres IX-X white, prothorax reddish, elytra metallic-green and
metatarsomeres I-IV white, Ommata (O.) albitarsis sp. nov. may be compared with Ommata (O.)
paradisiaca Tippmann, 1953. It differs by antennomere XI white with apical half black; prosternum, with
a black band next to each procoxa; mesofemora black with a narrow basal area reddish and elytra unicolor
(excepting the reddish basal line beside the scutellum).
Zajciw (1960:94) described the female of O. (O.) paradisiaca, previously recognized only through the
male, with the differential characters: antennomeres IV to VI black and antennae surpassing the elytral
apices by their last two articles (the remaining are secondary sexual characters). In O. (O.) paradisiaca,
antennomere XI is entirely white, the prosternum is entirely black, the basal halves of mesofemora are
white and the elytra present a yellowish longitudinal band, which gradually narrows from the base to the
middle.

length, 4.7; humeral width, 1.8.
Type material. Male holotype, BRAZIL, Bahia: São Félix do Coribe-Coribe, (km 24, 13o33’S 44o15’W,
493 m), 07.XII.2007, F. Bravo col. (UEFS).
Etymology. Latin, viridescens = which becomes green; allusion to the integument color.
Diagnosis. Cosmisoma viridescens sp. nov. could be compared with C. gratum Monné and Magno, 1988
by antennomere V, with small hair tuft on the apex; prothorax reddish; antennae and legs black, with
